Prognostic value of circulating tumor cells combined with neutrophil-lymphocyte ratio in patients with hepatocellular carcinoma

BACKGROUND Circulating tumor cell(CTC)count and neutrophil-to-lymphocyte ratio(NLR)are both closely associated with the prognosis of hepatocellular carcinoma(HCC).AIM To investigate the prognostic value of combining these two indicators in HCC.METHODS Clinical data were collected from patients with advanced HCC who received im-mune therapy combined with targeted therapy at the Department of Oncology,the Affiliated Hospital of Southwest Medical University,Sichuan,China,from 2021 to 2023.The optimal cutoff values for CTC programmed death-ligand 1(PD-L1)(+)>1 or CTC PD-L1(+)≤1 and NLR>3.89 or NLR≤3.89 were evaluated using X-Tile software.Patients were categorized into three groups based on CTC PD-L1(+)counts and NLR:CTC-NLR(0),CTC-NLR(1),and CTC-NLR(2).The relationship between CTC-NLR and clinical variables as well as survival rates was assessed.RESULTS Patients with high CTC PD-L1(+)expression or NLR at baseline had shorter median progression-free survival(m-PFS)and median overall survival(mOS)than those with low levels of CTC PD-L1(+)or NLR(P<0.001).Mean-while,patients in the CTC-NLR(2)group showed a significant decrease in mPFS and mOS.Cox regression analysis revealed that alpha-fetoprotein(AFP),CTC PD-L1(+),and CTC-NLR were independent predictors of OS.The time-dependent receiver operating characteristic curve showed that the area under the curve of CTC-NLR at 12 months(0.821)and 18 months(0.821)was superior to that of AFP and CTC PD-L1(+).CONCLUSION HCC patients with high CTC PD-L1(+)or NLR expression tend to exhibit poor prognosis,and a high baseline CTC-NLR score may indicate low survival.CTC-NLR may serve as an effective prognostic indicator for patients with advanced HCC receiving immunotherapy combined with targeted therapy.

Predictive Value of the Neutrophil to Lymphocyte Ratio (NLR) to Predict the Development of Preeclampsia and Pregnancy Induced Hypertension at 1st Trimester

Introduction: Hypertensive disorder in pregnancy affects 4 to 6 percent of all pregnancies and carries risks for the both baby and the mother. Only a few groups of women who are at high-risk pregnancies are received prophylaxis Aspirin, more than 15 percent of women develop pre-eclampsia with a single minor risk factor. Methods: This descriptive cross-sectional study was conducted to compare the 1st trimester NLR value of normotensive, pregnancy induced hypertensive and pre-eclamptic pregnant women. The study was conducted with a sample of 416, antenatal patients who were admitted to ward 25, at Colombo North Teaching Hospital Ragama. Data was collected as separated three groups. NLR value was calculated separately and ANOVA test was used to analyze the 3 categorical data. Post HOC test was done to assess the multiple comparison. Results: The prevalence rates of pregnancy induced hypertension and pre-eclampsia among the pregnant women were 8.6% and 5.7%. The mean NLR values of normotensive group was 2.708, pregnancy induced hypertensive group was 2.650 and pre eclamptic group was 3.789. There was a significant difference in NLR value between pre eclamptic group and other two groups with P value of Conclusion: The 1st trimester NLR value of pre eclamptic patients significantly increased compared to normotensive women.

Prognostic Value of Neutrophil to Lymphocyte Ratio in Acute Myeloid Leukemia

Objective: Acute myeloid leukemia (AML) is a heterogeneous, hematologic malignancy at which short survival may be seen. Our study aims to evaluate the effect of the neutrophil-to-lymphocyte ratio (NLR) on the course of the disease, response to therapy, and overall survival (OS). Materials and Methods: A total of 124 patients followed-up with the diagnosis of AML from 2016 to 2019 were retrospectively examined. Results: 69 of the cases (55.6%) were men and 55 (44.3%) were women. The average age at the time of diagnosis was 53.44 ± 30.3 years old. We determined the NLR as median 0.46 (0.16 - 1.1). In AML, 69 patients were responsive to the induction regimen (57.9%) while 46 patients were unresponsive (37.8%). 5 patients died before completing the regimen. D-dimer was found to be higher and fibrinogen was found to be lower in the responsive group. Lower OS was observed in cases of >60 years of age, male gender, non-APL AML, high NLR, and recurrence at diagnosis. Recurrences were detected in 23 patients (18.5%) and the median time to the recurrence was 416 (236 - 639) days. Fibrinogen level and the bone marrow blast ratio at the time of application were determined to be associated with recurrence. The median follow-up time was 856 (143 - 1276) days. Final condition analysis reveals that 74 patients (59.6%) are alive. Conclusion: We determined in our study that the NLR is effective on survival. Medical literature on this subject is scanty and prospective studies with large patient groups are needed.

Predictive model for non-malignant portal vein thrombosis associated with cirrhosis based on inflammatory biomarkers

BACKGROUND Portal vein thrombosis(PVT),a complication of liver cirrhosis,is a major public health concern.PVT prediction is the most effective method for PVT diagnosis and treatment.AIM To develop and validate a nomogram and network calculator based on clinical indicators to predict PVT in patients with cirrhosis.METHODS Patients with cirrhosis hospitalized between January 2016 and December 2021 at the First Hospital of Lanzhou University were screened and 643 patients with cirrhosis who met the eligibility criteria were retrieved.Following a 1:1 propensity score matching 572 patients with cirrhosis were screened,and relevant clinical data were collected.PVT risk factors were identified using the least absolute shrinkage and selection operator(LASSO)and multivariate logistic regression analysis.Variance inflation factors and correlation matrix plots were used to analyze multicollinearity among the variables.A nomogram was constructed to predict the probability of PVT based on independent risk factors for PVT,and its predictive performance was verified using a receiver operating characteristic curve(ROC),calibration curves,and decision curve analysis(DCA).Finally,a network calculator was constructed based on the nomograms.RESULTS This study enrolled 286 cirrhosis patients with PVT and 286 without PVT.LASSO analysis revealed 13 variables as strongly associated with PVT occurrence.Multivariate logistic regression analysis revealed nine indicators as independent PVT risk factors,including etiology,ascites,gastroesophageal varices,platelet count,D-dimer,portal vein diameter,portal vein velocity,aspartate transaminase to neutrophil ratio index,and platelet-to-lymphocyte ratio.LASSO and correlation matrix plot results revealed no significant multicollinearity or correlation among the variables.A nomogram was constructed based on the screened independent risk factors.The nomogram had excellent predictive performance,with an area under the ROC curve of 0.821 and 0.829 in the training and testing groups,respectively.Calibration curves and DCA revealed its good clinical performance.Finally,the optimal cutoff value for the total nomogram score was 0.513.The sensitivity and specificity of the optimal cutoff values were 0.822 and 0.706,respectively.CONCLUSION A nomogram for predicting PVT occurrence was successfully developed and validated,and a network calculator was constructed.This can enable clinicians to rapidly and easily identify high PVT risk groups.

Prognostic Value of Neutrophil to Lymphocyte Ratio for In-hospital Mortality in Elderly Patients with Acute Myocardial Infarction

Coronary artery disease （CAD） is a multifactorial disease in which inflammation plays a central role. This study aimed to investigate the association of inflammatory markers such as the neutrophil to lymphocyte ratio （NLR）, the Global Registry of Acute Coronary Events （GRACE） score with in-hospital mortality of elderly patients with acute myocardial infarction （AMI） in an attempt to explore the prognostic value of these indices for elderly AMI patients. One thousand consecutive CAD patients were divided into two groups based on age 60. The laboratory and clinical characteristics were assessed retrospectively by reviewing the medical records. The NLR and GRACE score were calculated. In the elderly （〉60 years）, patients with non-ST-elevation myocardial infarction （NSTEMI） and ST-elevation myocardial infarction （STEMI） had significantly higher NLR than did those with unstable angina （UA） and stable angina pectoris （SAP） （P〈0.01）. The NLR was considerably elevated in older AMI patients compared with their younger counterparts （〈60 years） （P〈0.05）. In elderly AMI patients, the NLR was considerably higher in the high-risk group than in both the low-risk and mediumrisk groups based on the GRACE score （P〈0.05 and P〈0.01, respectively）, and the NLR was positively correlated with the GRACE score （r=0.322, P〈0.001）. Either the NLR level or the GRACE score was significantly higher in the death group than in the surviving group （P〈0.05）. By curve receiver operator characteristic curve （ROC） analysis, the optimal cut-off levels of 9.41 for NLR and 174 for GRACE score predicted in-hospital death [ROC area under the curve （AUC） 0.771 and 0.787, respectively, P〈0.001]. It was concluded that an elevated NLR is a potential predictor of in-hospital mortality in elderly patients with AMI.

Preoperative Neutrophil Lymphocyte Ratio and Platelet Lymphocyte Ratio Cannot Predict Lymph Node Metastasis and Prognosis in Patients with Early Gastric Cancer：a Single Institution Investigation in China

In the present study,we aimed at exploring the applied value of preoperative neutrophil lymphocyte ratio（NLR） and platelet lymphocyte ratio（PLR） in the prediction of lymph node metastasis（LNM） and prognosis in patients with early gastric cancer（EGC）.We retrospectively analyzed a total of 248 consecutive patients who underwent curative gastrectomy to be identified T1 stage gastric adenocarcinoma between January 1,2010 and May 1,2016 in a single institution.According to median preoperative NLR and PLR value,we divided the patients into four groups：high NLR ≥1.73 and low NLR 〈1.73,high PLR ≥117.78 and low PLR〈 117.78.Furthermore,to evaluate the relationship between preoperative NLR and PLR values,we categorized patients according to cutoff preoperative NLR-PLR score of 2 [high NLR（≥1.73） and high PLR（≥117.78）],1 [either high NLR or high PLR],and 0 [neither high NLR nor high PLR].Statistical analyses were conducted using SPSS 20.0 software.The results showed that the preoperative NLR or PLR values,lower or higher,could not predict the LNM in patients with EGC（both P=0.5440.05）.The invasive depth of tumor was significantly correlated with LNM of EGC（P〈0.001）.Kaplan-Meier plots illustrated that preoperative NLR and PLR values were not associated with overall survival（OS） in patients with EGC.It was concluded that the preoperative NLR and PLR may be the predictors for LNM and prognosis in patients with advanced gastric cancer;nevertheless,they cannot predict LNM and prognosis in patients with EGC.

Urine microscopy and neutrophilelymphocyte ratio are early predictors of acute kidney injury in patients with urinary tract infection

Objective:Urinary tract infection(UTI)is a common cause of morbidity and hospitalisation in the population worldwide.Upper UTI is indolent and causes subclinical acute kidney injury(AKI)resulting in preventable cause of scarring of renal parenchyma.We explored urinary and serum levels of kidney injury molecule-1(KIM-1),haematological parameters and quantitative urine microscopy parameters to predict kidney injury.Methods:Neutrophilelymphocyte ratio(NLR)is obtained by dividing absolute neutrophil count with absolute lymphocyte count.Quantitative urine sediment microscopy was performed and correlated with clinical,biochemical and haematological findings to predict AKI in patients with UTI.Quantitative ELISA was performed for serum and urine levels of KIM-1.Seventy two adult patients with UTI were enrolled,45 of whom had AKI while 27 were in the non-AKI group.Results:NLR(p=0.005)and renal tubular epithelial cell-granular cast score in quantitative urine microscopy(p=0.008)are strong predictors of AKI in patients with UTI while rest of quantitative urine microscopy parameters and serum and urinary levels of KIM-1 molecule were not found to be useful in prediction of AKI.Conclusion:NLR in haemogram is a novel and useful biomarker for predicting AKI in patients with UTI.

Neutrophil to lymphocyte ratio and albumin bilirubin grade in hepatocellular carcinoma: A systematic review

BACKGROUND Hepatocellular carcinoma(HCC)is a frequent cause of cancer related death globally.Neutrophil to lymphocyte ratio(NLR)and albumin bilirubin(ALBI)grade are emerging prognostic indicators in HCC.AIM To study published literature of NLR and ALBI over the last five years,and to validate NLR and ALBI locally in our centre as indicators of HCC survival.METHODS A systematic review of the published literature on PubMed of NLR and ALBI in HCC over the last five years.The search followed the guidelines of the preferred reporting items for systematic reviews and meta-analyses.Additionally,we also investigated HCC cases between December 2013 and December 2018 in our centre.RESULTS There were 54 studies describing the relation between HCC and NLR and 95 studies describing the relation between HCC and ALBI grade over the last five years.Our local cohort of patients showed NLR to have a significant negative relationship to survival(P=0.011).There was also significant inverse relationship between the size of the largest HCC nodule and survival(P=0.009).Median survival with alpha fetoprotein(AFP)<10 KU/L was 20 mo and with AFP>10 KU/L was 5 mo.We found that AFP was inversely related to survival,this relationship was not statically significant(P=0.132).Mean survival for ALBI grade 1 was 37.7 mo,ALBI grade 2 was 13.4 months and ALBI grade 3 was 4.5mo.ALBI grades performed better than Child Turcotte Pugh score in detecting death from HCC.CONCLUSION NLR and ALBI grade in HCC predict survival better than the conventional alpha fetoprotein.ALBI grade performs better than Child Turcotte Pugh score.These markers are done as part of routine clinical care and in cases of normal alpha fetoprotein,these markers could give a better understanding of the patient disease progression.NLR and ALBI grade could have a role in modified easier to learn staging and prognostic systems for HCC.

Association between neutrophil-to-lymphocyte ratio and major postoperative complications after carotid endarterectomy:A retrospective cohort study

BACKGROUND Carotid artery cross-clamping during carotid endarterectomy(CEA)may damage local cerebral perfusion and induce cerebral ischemia–reperfusion injury to activate local inflammatory responses.Neutrophil-to-lymphocyte ratio(NLR)is an indicator that reflects systemic inflammation.However,the correlation between NLR and complications after CEA remains unclear.AIM To investigate the association between NLR and major complications after surgery in patients undergoing CEA.METHODS This retrospective cohort study included patients who received CEA between January 2016 and July 2018 at Beijing Tiantan Hospital.Neutrophil and lymphocyte counts in whole blood within 24 h after CEA were collected.The primary outcome was the composite of major postoperative complications including neurological,pulmonary,cardiovascular and acute kidney injuries.The secondary outcomes included infections,fever,deep venous thrombosis,length of hospitalization and cost of hospitalization.Statistical analyses were performed using EmpowerStats software and R software.RESULTS A total of 224 patients who received CEA were screened for review and 206 were included in the statistical analyses;of whom,40(19.42%)developed major postoperative complications.NLR within 24 h after CEA was significantly correlated with major postoperative complications(P=0.026).After confounding factors were adjusted,the odds ratio was 1.15(95%CI:1.03–1.29,P=0.014).The incidence of major postoperative complications in the high NLR group was 8.47 times that in the low NLR group(P=0.002).CONCLUSION NLR is associated with major postoperative complications in patients undergoing CEA.

Usefulness of the Pediatric Appendicitis Score and Neutrophil to Lymphocyte Ratio for Assessing the Complicated Appendicitis in Children

Introduction: Acute appendicitis (AA) is a common surgical disease which occurs in almost all age groups, and especially in childhood. Acute appendicitis is one of the most common causes of acute abdomen. The lifetime occurrence of this disease is approximately 7%, with perforation rate of up to 20%. In spite of the well-known classical symptoms and clinical findings of acute appendicitis, early diagnosis can be sometimes challenging. For the treatment of simple appendicitis (SA) in children, the effectiveness of antibiotic treatment has been reported. We aimed to determine predictive value of combination NLR and PAS in pediatric patients with clinical suspicion of acute appendicitis and complicated appendicitis Methods: Our study was performed on 480 children admitted for suspected acute appendicitis and underwent appendectomy at the MNCMCH, Ulaanbaatar Mongolia, between May 2019 and December 2019. White blood count (WBC), Neutrophil, NLR and PAS were compared between groups. Results: The sensitivity, specificity, PPV, NPV of PAS + NLR for differentiating complicated and noncomplicated appendicitis were 86.8%, 89.4%, 92.1% and 76% respectively. The sensitivity, specificity, PPV, NPV of PAS + NLR for diagnosis of acute appendicitis were 90.5%, 68.1%, 97.68% and 32.6% respectively. Conclusion: In the era of conservative antibiotic-based management of uncomplicated acute appendicitis, we advocate that combination of NLR and PAS is a useful aid in predicting complicated appendicitis.

Diagnostic and prognostic significance of the lymphocyte/C-reactive protein ratio,neutrophil/lymphocyte ratio,and D-dimer values in patients with COVID-19

In this study,our aim was to examine the diagnostic and prognostic significance of lymphocyte/C-reactiveprotein ratio(LCR),neutrophil/lymphocyte ratio(NLR)and D-dimer parameters in COVID-19 infection.The LCR,NLR,neutrophil count,mean platelet volume(MPV),C-reactive protein(CRP),and D-dimer parameters wereevaluated retrospectively.This was a retrospective cohort study with 1000 COVID-19 positive and 1000 healthycontrol groups,all over the age of 18 years.Odds ratio(OR)and 95%confidence interval(CI)values were calculatedfor each parameter found to be statistically significant in the univariate and multivariate logistic regression models.Herein,127(12.7%)of the COVID-19^(+)patients,whose data was included in this study,died.The neutrophil,MPV,CRP,D-dimer,and NLR values were higher in the COVID-19^(+)/deceased group than in the COVID-19^(+)/alive andcontrol groups(p<0.001,p<0.001,p<0.001,p<0.001,p<0.001).The lymphocyte and LCR values were lower inthe COVID-19^(+)/deceased group than in the COVID-19^(+)/alive and control groups(p<0.001,p<0.001).Variableswith statistically significance in predicting COVID-19 infection were lymphocyte,LCR,D-dimer,NLR,CRP,MPV,PLT,and neutrophil values.Statistically significant variables in predicting mortality due to COVID-19 were LCR,CRP,NLR,lymphocyte,D-dimer,neutrophil,and MPV values.A low LCR and high NLR are associated with thepresence,prognosis,and mortality due to COVID-19.LCR and NLR parameters can thus be used in clinicalmonitoring to reduce morbidity and mortality rates.

Relationship between peripheral blood neutrophil/lymphocyte ratio and the prognosis of patients with brittle femoral neck fracture

Objective:To explore the relationship between peripheral blood neutrophil/lymphocyte ratio(NLR)and osteoporotic femoral neck fractures and to evaluate the prognosis.Methods:The subjects were 102 patients who received osteoporotic femoral neck fracture in the First Affiliated Hospital of Guangzhou University of Chinese Medicine from 2008 to 2017.Patients were divided into three groups according to the BMD values in the diagnostic criteria of primary osteoporosis:normal bone mass group(T≥-1.0),reduced bone mass group(-2.5<T<-1.0)and osteoporosis group(T≤-2.5).In addition,during postoperative follow-up,patients receiving internal fixation were divided into the high NLR group(NLR>2.33)and the low NLR group(NLR≤2.33)according to their NLR values.The clinical data of patients with osteoporotic femoral neck fracture who underwent peripheral blood routine examination were prospectively analyzed.The statistical indicators included age,gender,fracture cause and other general conditions,fracture type,peripheral blood neutrophil/lymphocyte ratio,bone mineral density(BMD)level and blood lipid level,and prognosis of 102 patients who were followed up for more than 2 years after surgery.The relationship between peripheral blood NLR and the above indexes was observed.Statistical methods including normal data analysis of variance between groups,SNK-q test is compared between two groups,the partial correlation analysis between the two factors,the relationship between multiple factors using multi-factor linear regression analysis,and normal data comparison between the two groups using t test,two sets of independent data frequency distribution of binary classification variables compared by chi-square test.Moreover,NLR is also a major factor affecting the prognosis and rehabilitation of osteoporotic femoral neck fractures.Results:The analysis of variance between the two groups(SNK-q test of the comparison between the two groups),single-factor partial correlation analysis,multi-factor linear regression analysis showed that compared with the normal group and the reduced group,the levels of age,triglyceride and NLR in the osteoporosis group were increased,while BMD was significantly decreased.BMD in patients with osteoporotic femoral neck fracture was negatively correlated with NLR and triglyceride(P<0.05).In multi-factor linear regression analysis,NLR and triglyceride were the main influencing factors of BMD in patients with osteoporotic femoral neck(P<0.05).In addition,increased peripheral blood NLR in patients treated with internal fixation may increase the risk of postoperative femoral head necrosis,nonunion of the broken end of the fracture,and prolong the time of postoperative functional recovery.Conclusion:The level of peripheral blood NLR in patients with osteoporotic femoral neck fracture is increased and correlated with bone mineral density,which suggested that peripheral blood NLR can be used as one of the clinical indicators for early screening and prevention of osteoporotic femoral neck fracture.In addition,peripheral blood NLR is also a major factor affecting the prognosis and rehabilitation of osteoporotic femoral neck fractures.

Can the neutrophil-lymphocyte ratio, platelet-lymphocyte ratio and lymphocyte-monocyte ratio predict active bleeding in patients with upper gastrointestinal bleeding?

Objective:To investigate the relationship between upper gastrointestinal bleeding and neutrophil-lymphocyte ratio(NLR),platelet-lymphocyte ratio(PLR),and lymphocyte-monocyte ratio(LMR),and examine whether they can be used as markers of inflammation.Methods:The retrospective single-center study included a total of 189 patients with upper gastrointestinal bleeding admitted to the tertiary emergency department between January 2018 and January 2019.Besides,59 patients with similar demographic characteristics were selected as the control group.Besides,42 patients with active bleeding and 147 patients without active bleeding were categorized into two groups according to their endoscopy reports.The NLR,PLR,LMR values,potential risk factors,and demographic characteristics were analyzed.Results:The mean NLR levels were found significantly higher in the patient group compared to the control group(P<0.001),whereas the mean LMR levels were significantly lower in the patient group(P<0.001).The mean NLR and PLR levels were significantly higher in patients with active bleeding compared to those without active bleeding(P<0.001),whereas the mean LMR levels were significantly lower(P<0.001)for patients with active bleeding.The optimal cut-off value of NLR was found 2.1 for predicting uppergastrointestinal bleeding,with a sensitivity of 80.2%and specificity of 78.9%(AUC:0.840;P<0.001).Conclusions:NLR was determined to be a parameter that can be used as an indicator of active bleeding in patients with upper gastrointestinal bleeding.

The Clinical Value of NLR, D-D and CRP/ALB Ratio in the Diagnosis of Pulmonary Thromboembolism

Objective: To evaluate the clinical diagnostic value of C-reactive protein/albumin ratio (CAR), neutrophil/lymphocyte ratio (NLR) and D-dimer (D-D) in patients with pulmonary thromboembolism (PTE). Methods: We conducted a retrospective analysis comparing hematology and coagulation in 362 PTCA-confirmed PTE patients with the control group and analyzing their relationships with CAR, NLR, and D-D. Receiver operating characteristic curve (ROC) was used to analyze the diagnostic threshold, area under the curve (AUC), diagnostic sensitivity and specificity of CAR, NLR and D-D for PTE. Results: 1) CAR, NLR and D-D levels in PTE patients were 2.13 ± 2.08, 8.96 ± 1.94 and 9.69 ± 8.61 respectively, significantly higher than those in control group (CAR = 0.03 ± 0.01, t = 20.7736, P < 0.01;NLR = 1.76 ± 0.53, t = 2.4281, P < 0.05 and PTE = 0.20 ± 0.11, t = 3.0066, P < 0.01 respectively). 2) NLR was positively correlated with CAR (r = 0.2111, t = 4.0971, P < 0.01) and D-D (r = 0.1065, t = 2.0481, P < 0.05), but CAR was not correlated with D-D (r = 0.0975, P > 0.05). 3) The levels of HB, LY, PLT and AT in PTE patients were significantly lower than those in control group, while WBC, NE and FB were significantly higher than those in control group. 4) CAR was negatively correlated with Hb and AT (P all < 0.01), but positively correlated with WBC, NE, MO and FB (P all < 0.01). NLR was negatively correlated with LY and AT (P all < 0.01), but positively correlated with WBC, NE and FB (P all < 0.01). DD was negatively correlated with Hb and PLT (P all < 0.05), but positively correlated with WBC, NE and MO (P all < 0.01). Conclusion: The levels of Hb, LY, PLT and AT were significantly decreased in PTE patients, while WBC, NE and FB were significantly increased. CAR, NLR and D-D were highly expressed in PTE patients, and were closely correlated with Hb, AT and FB. Combined detection of CAR, NLR and D-D can improve the diagnostic value of PTE.

Neutrophil Lymphocyte Ratio as an Inflammatory Marker in Chronic Kidney Disease: Determinants and Correlates

Introduction: Inflammation has been implicated as a major reason for the higher morbidity and mortality in chronic kidney disease (CKD) compared to the diseases that commonly precedes it. The neutrophil lymphocyte ratio (NLR) has increasingly been reported to be a marker of systemic inflammation. We studied the neutrophil lymphocyte ratio and its relationship with kidney function and other markers of inflammation in health and in CKD. Methods: Two hundred and forty four participants in three cohorts: healthy, CKD stage 1 - 2 and, stage 3 - 4, were studied. Data of clinical, NLR, uric acid, urine albumin creatinine ratio (UACR), electrolytes were documented and independent associates of NLR were determined. Results: The NLR was higher in the CKD cohorts, P Conclusion: The NLR as an inflammatory marker is elevated in chronic kidney disease, and increases with disease severity hence it can be a useful tool in determining the presence and severity of inflammation in CKD.

Neutrophil to Lymphocyte Ratio in Acute Ischemic Stroke

Introduction: The neutrophil to lymphocyte ratio (NLR) can be used as a marker of subclinical inflammation, and may have a predictive power in prognosis and severity of atherosclerosis-related diseases. This study aimed to assess an association between the NLR, and clinical characteristics and one-month outcome in acute ischemic stroke (AIS). Subjects and Methods: This case-control observational prospective study included 75 patients admitted to stroke unit of Ain Shams University hospitals with AIS, sub grouped into 3 equal groups according to subtype of AIS, in addition to 25 healthy individuals. The demographic characteristics of the patients, complete blood picture test results at presentation, National Institutes of Health Stroke Scale (NIHSS) scores and modified Rankin Scale (mRS) scores were recorded. The clinical outcome was assessed by the NIHSS and mRS scores after one month. Results: The total leucocyte count was significantly higher in large artery atherosclerosis (P = 0.004) and cardioembolic (P = 0.020) stroke groups, unlike lacunar stroke group (P = 0.082), when compared to controls. The neutrophils count was higher (P < 0.001) and the lymphocyte count was lower (P < 0.001) among all the stroke groups compared to the control group. The NLR was higher among all the stroke groups compared to the control group (P < 0.001). The NLR at cutoff value more than 1.34 had predicted stroke with a sensitivity of 89.33% and specificity of 72% and accuracy reached 88.6%. There was non-significant association between NLR and each of NIHSS and mRS after one month from onset of AIS. Conclusion: NLR was significantly higher among AIS subtypes compared to controls, but not a good predictor for one month outcome.

Therapeutic Effect of Daphnetin on Mastitis Induced by Staphylococcus aureus in Mice

[Objectives]To observe the effects of daphnetin on mastitis induced by Staphylococcus aureus in mice.[Methods]18 postpartum ICR female mice were used to establish mastitis animal model,and were randomly divided into three groups(A,B,and C)with 6 mice in each group.Group A:blank control group;group B:S.Aureus model group;group C:S.Aureus model+daphnetin group.The experimental groups were injected 1 mL of 1.0×104 CFU/100μL of S.aureus of along the nipple catheter.The suspension was placed in the 3 rd and 4 th pairs of mammary glands,and the control group was injected with the same dose of normal saline.On the second day after infection,the rats in group A,B and C were given drugs by gavage,while the rats in group A and B were given normal saline and the rats in group C were given daphnetin once a day for 6 consecutive days.Blood samples were collected from living eyeballs,and blood cells were analyzed by automatic flow cytometer after anticoagulation.[Results]The NLR and Systemie Immune Inflammati-on Index(SII)in the blood of mastitis mice induced by S.aureus were significantly higher than those in the control group(P<0.01),suggesting that neutrophil to lymphocyte ratio(NLR)and SII can be used as diagnostic indicators of mastitis,and the levels of NLR and SII decreased significantly after daphnetin intervention.[Conclusions]NLR and SII showed high levels in mastitis mice,which are valuable for the diagnosis of mastitis and the evaluation of its prognosis.After the intervention of daphnetin,both of them decreased significantly,indicating that daphnetin has a good prognosis trend in mastitis mice induced by S.aureus.

Inflammatory response related scoring systems in assessing the prognosis of patients with pancreatic ductal adenocarcinoma:a systematic review

BACKGROUND： Various scoring systems based on assessment of the systemic inflammatory response help assessing the prognosis of patients with pancreatic ductal adenocarcinoma.In the present systematic review we evaluated the validity of four pre-intervention scoring systems： Glasgow prognostic score（GPS） and its modified version（mGPS）, platelet lymphocyte ratio（PLR）, neutrophil lymphocyte ratio（NLR）, and prognostic nutrition index（PNI）.DATA SOURCES： MOOSE guidelines were followed and EMBASE and MEDLINE databases were searched for all published studies until September 2013 using comprehensive text word and MeSH terms. All identified studies were analyzed, and relevant studies were included in the systematic review.RESULTS： Six studies were identified for GPS/mGPS with3 reporting statistical significance for GPS/mGPS on both univariate analysis（UVA） and multivariate analysis（MVA）.Two studies suggested prognostic significance on UVA but not MVA, and in the final study UVA failed to show significance.Eleven studies evaluated the prognostic value of NLR. Six of them reported prognostic significance for NLR on UVA that persisted at MVA in 4 studies, and in the remaining 2 studies NLR was the only significant factor on UVA. In the remaining5 studies, all in patients undergoing resection, there was no significance on UVA. Seven studies evaluated PLR, with only one study demonstrated its prognostic significance on both UVAand MVA, the rest did not show the significance on UVA. Of the two studies identified for PNI, one demonstrated a statistically significant difference in survival on both UVA and MVA, and the other reported no significance for PNI on UVA.CONCLUSIONS： Both GPS/mGPS and NLR may be useful but further better-designed studies are required to confirm their value. PLR might be little useful, and there are at present inadequate data to assess the prognostic value of PNI. At present, no scoring system is reliable enough to be accepted into routine use for the prognosis of patients with pancreatic ductal adenocarcinoma.

Association between routine hematological parameters and sudden sensorineural hearing loss:A meta-analysis

Objective:Recent studies have shown that chronic inflammation contributes to the development of sudden sensorineural hearing loss(SSNHL).Some hematologic parameters have also been linked to the prognosis of SSNHL.However,the prognostic value of such hematological factors is not conclusive.This study explored the association of routine hematological parameters with SSNHL.Methods:A systematic literature search was conducted in PubMed,Cochrane Library,Web of Science and Embase to identify eligible studies.Standardized mean deviation(SMD)and the 95%confidence interval(CI)were retried from relevant studies for analysis.Heterogeneity,subgroup,and publication bias analyses were performed.Results:A total of 18 studies involving 1505 SSNHL patients and 1466 healthy persons were enrolled in the final analysis.The study population included 699 responders and 458 non-responders to treatment.Pooled results revealed that the neutrophil/lymphocyte ratio(NLR)and platelet/lymphocyte ratio(PLR)value in the SSNHL patient group were higher than in the healthy group(SMD=1.05,95%CI:0.86,1.24,p<0.001,SMD=0.52,95%CI:0.26,0.78,p<0.001,respectively).However,there was no significant difference in the mean platelet volumes(MPV)between the groups(SMD=0.03,95%CI:0.44,0.49,p=0.91).Notably,NLR and PLR values were evidently higher in the unrecovered group than in the recovered group(SMD=0.63,95%CI:1.02,0.23,p=0.002,SMD=0.4,95%CI:0.76,0.03,p=0.03,respectively).However,the MPV value was similar in both groups(SMD=0.35,95%CI:1.14,0.44,p=0.38).Conclusions:Our results show that NLR and PLR values can predict the onset and prognosis of SSNHL.
